San Francisco’s Board of Supervisors approved unanimously an ordinance that that allows developers of residential projects to exceed parking caps by adding designated car sharing spaces.

Supervisor Scott Wiener introduced the proposal last year with aims to promote car sharing.

The ordinance states that the parking spaces will be available at no cost to the car share organizations, and can be used for other purposes if a car share organization does not elect to use the space. The ordinance also outlines how many spaces can be included depending on the number of units that will be built in the residential development.

In the past, developers have been discouraged to save parking spots for car sharing vehicles since it would count toward their maximum number of allowed spaces.
